An easier explanation

Hi, is there an easier explanation for this question? Since it's the last question, I'm usually down to the wire, or I'm having to guess. Are there are any tricks or hints for these types of questions? I know these are supposed to be hard, but sometimes they seem impossible with the time remaining.

One way to simplify rule replace,ent questions is to think about it in terms of what would force the original rule to be true. That is, we are looking for an answer choice that can give us the initial rule as a deduction. We are trying to find something that forces F and H to not go together.

E does this exactly. E means that at least one of IG must be in every city. This means there will never be enough space for FH to go to gather.
